Perfect for beadwork, Nymo Thread is much stronger than cotton sewing thread. Nymo thread is easy to thread, lightly waxed and is the perfect choice for seed bead projects such as looming and stitching. Size B threads measure 0.2mm or 0.008 Inch thick and are great for seed bead sizes 12/0, 11/0 and 08/0 and needle sizes #11 and #10. Try to use the largest size thread permitted by your beads for the best strength.
